Study sheds new light on extinction risk in mammals

Researchers have long assumed that habitat fragmentation contributes to extinction risk for animals, but until now, they have not been able to measure it for a major group of animals on a global scale. In a first-of-its-kind study, an international research team led by Colorado State University successfully measured habitat fragmentation for over 4,000 species of land-dwelling mammals. Among the findings, researchers discovered that species with more habitat fragmentation are at greater risk of extinction.
